Patented Feb. 5, 1935 UNITED STATES PATENT OFFICE 7 Claims.

This invention embodies novel improvements in Weatherstrip constructions of the class particularly designed for use upon outwardly opening casement windows.

An essential object of the invention has'been to design Weatherstrip means of the class set forth embodying provisions for effectively preventing the entry of water, .air and/or foreign matter between the sill portions'of a window, and the outwardly swinging casement windows mounted thereabove. So far as I am aware, prior commercial constructions in use today do not prevent adequately and efficiently the entrapment of water upon Weatherstrip means such ascustomarily provided between the window or windows, and the sill of the window frame in which they are mounted.

My invention includes, among other objects, a design of Weatherstrip means of the utmost simplicity of construction, as regards the Weatherstrip parts themselves, and one in which the method of applying the Weatherstrip means to the sill and to the window parts is greatly simplified so as to facilitate installation.

Another feature 'ofmy invention resides in the formation of the window strip memberi in' such'a manner asto cooperate with the sill strip member'to aff'or'dan effective double sealing action between the parts;

The" foregoing, with other objects appertaining to the detailed structure of my invention, are achieved by the preferred forms of-the invention that are illustrated in'the'accompanying drawing; :in-which:

Figure 1' is atransverse sectional view of my Weatherstrip construction," showing one adaptation of the invention wherein the sill Weatherstrip member is preferably an extruded structure.

Figure 2 is asectional fragmentary perspective View of the window strip member according to the form of the invention of Figure 1.

Figures is a view similarto Figure 2, but show ing the sill Weatherstrip member.

Figure i'i's a'view similar to Figure 1, illustrat i'ng a'modification'of the invention in which the sill member of the Weatherstrip means is made of sheet metal, a modified adaptation of the construction of Figures 1 to 3 inclusive.

Figure 5 is a viewfsimilar to' Figure 4, showing still another modification ofmy' invention.

Figures 6 and 7 are perspective views like Figures 2 and 3, but showing the sill Weatherstrip members of Figures Land 5 respectively.

p Referringto Figure 1 of the-drawing, Adenotes the sill of a window frame, or the like; said sill being equipped with the stop strip B after the customary manner, and the window illustrated, being of the easement type adapted to swing outwardly in opening, and to the position of Figure 1; when closed.

Mounted upon the sill A at the corner established by the juncture between the sill A-and the stop strip B, is the sill Weatherstrip member 1, the same comprising a base portion, having a vertical or upwardly extending wall 2, from which outwardly projects a sealing flange 3. The sealing flange 3 is arranged to cooperate with the window sealing member which comprises the attachment portion 2 secured by nails or other fastenings means 5 to the inner side of the wine dew and preferably counter-sunk so as to lie flush with said inner side and to avoid providing an obstruction of the close fitting contact of the lowest portion of the window, with the stop strip B. The attachment portion 4 of the window strip is formed with a U-shaped flange compris i ing an upper portion 6 and a lower portion 7, these portions 6 and '7 providing sealing elements above andbelow, respectively, to the sealing flange 3. For stiffening the free edge of the U'- shaped membercomprising the parts-6 and '7, the metal of said edge is folded upon itself, as shown at' by being bent outwardly upon itselfso that the topportion of the bend lies fiat against the un dersideofthe flange 3.

The base portion of the sill strip 1 may be screwed or otherwise fastened to the sill'A; and this portion of said sill strip is preferably. inclined at aslight angle downwardly inrelation to the wall or vertical portion 2, the inclination being'purposeful in that it prevents entrapment of any water'or foreign matter: that might pass between'the' window and sill strips in the use of the invention; Such water by the construction set forth; will freely flow outwardly and down wardly. into and from the space between the'bottomedge portions of the window or windows C and the sill A.

For facilitating the efiective securing of the sill strip 1 in position, I. preferably form asharp inwardly extending lip 3a in substantiallythe horizontal plane of the upper side of the flange '3 and adapted-to bite into the surface of the'stop strip B; Likewise at the lower outer edge of the base of the sill strip 1, I provide a similar lip-1a adapted to be pressed into and thus bite'into the upper surface of the sill A, to assist in prop-- erly positioning the sill strip inrelation to the parts A and B.

In the modification of my invention shown in window or windows C.

Figures 4 and 6, the sill strip 9 is made of sheet metal formed with a biting lip 10 similar to la previously set forth and bent upwardly to provide the vertical wall portion 11, thereupon being folded outwardly with a U-shaped fold 12 to proable and its edge 12a projects a short distance beyond the vertical plane of the wall portion 11 so as to ensure the desired sealing contact of the part 12a with the stop B. The pressure downward on the resilient base portion 9 by the sill attaching fastenings is eiiective to maintain the said contact of the part 12a. I New in Figures 5 and 7, I illustrate a construction which is similar to those previouslydescribed as to the general parts, but essentially similar to the construction of Figures i and e in that the sill strip comprises practically the same parts as the Figures 4 and 6 construction.

Thus, in Figure 5, it will be seen that the U- shaped sealing flange 13 of the sill strip is provided with a vertical sealing flange 14:, parallel with the vertical portion 15 that corresponds withthe wall 2 of the construction in Figure 1.

The sealing flange 14 is adapted to slide vertically on the stop strip B, and is, therefore, capable of permitting the adjustment vertically of the sill flange 13 to'thelocation of the window strip meansco-mprising the U-shaped sealing member, or flange 6, which is employed in all of the various modified forms of my invention.

. It is notable that in the mounting of the sealing members of my Weatherstrip means, as described in reference vto each construction presented above, that the sealing members of the window and sill we'atherstrips are received in a rabbeted portion or space 16 provided by the cutting away of the innerlower corneredge, so to speak, of the In other words, the rabbeted portions 16 of the window C receive practically speaking the parts 3, 6, 7 and 2 of the Weatherstrip construction of Figure 1, and'the corresponding parts of the Weatherstrip constructionsof the modified forms of my invention. a

From the foregoing, it will be apparent that the operation of installation of the parts of my Weatherstrip means is exceedingly simple, it only being necessary to provide on the lower edge portions'of the window the rabbeted portion 16 and the Very shallow groove or recess that is designed to receive the part 4 comprising the attachment portion of the window sealing member of my invention. In so far as the general cooperation ofthe parts are concerned, it is evident that this cooperation is much the same in'refer- I ence to both the extruded metal form of sill'strip illustrated in Figures 1 and 3, andthe sheet metal forms of said sill strip illustrated in Figures 41 to V 7, inclusive.

While I have described my invention and claimed it as used in conjunction with'outwardly opening casement windows,- -I do not wish to: be limited only to such specific application for'the construction set forth'may be employed in equivalent places. Thus my Weatherstrip structure is susceptible of use on the swinging or free'vertical edge portions of inswinging and outswinging casement windows as well as on the sill edges, so to speak, and such disposition is contemplated within the purview of the invention and the appended claims. In the latter construction, the

so-called sill strip would either be applied to the part of the window carrying the main weatherstrip part, or applied to an intermediate stop or bar provided between the edges of two coacting windows. The sill strips described are main strips, and the window carried strips are complementalstrips as readily evident.
